Thematic analysis of Prevention of Future Death reports for suicide: January 2021 to October 2022.

BACKGROUND: Suicide prevention remains a high priority topic across government and the National Health Service (NHS). Prevention of Future Death (PFD) reports are produced by coroners to highlight concerns that should be addressed by organisations to prevent future deaths in similar circumstances. OBJECTIVE: This research aimed to understand themes from concerns raised in PFD reports for deaths from suicide to inform future policies and strategies for preventing suicide. METHODS: We employed a retrospective case series design to analyse PFD reports categorised as suicide using qualitative inductive thematic analysis. Primary themes and subthemes were extracted from coroners' concerns. Following theme extraction, the number of concerns coded to these themes across reports and the frequency of recipient organisation being named as addressee on these reports were assessed as primary outcomes. FINDINGS: 12 primary themes and 83 subthemes were identified from 164 reports (4% of all available reports). The NHS was the most frequent recipient of these reports, followed by government departments. Coroners raised issues around processes within or between organisations and difficulties accessing services. The most common concerns fell under the primary theme 'processes' (142 mentions), followed by 'access to services' (84 mentions). The most frequent subthemes were 'current training not adequate' (38 mentions) and 'inadequate communication between services' (35 mentions). CONCLUSIONS: Our results specify areas where review, improvement and policy development are required to prevent future suicide deaths occurring in similar circumstances. CLINICAL IMPLICATIONS: These themes highlight concerns across current care and service provision where reform is required for suicide prevention.

Utah Latina/o/x suicide decedents less likely to die by firearm, even in rural areas: examining population-wide data from the Utah Office of the Medical Examiner.

Introduction: Suicide death remains a significantly rarer event among Latina/o/x populations compared to non-Latina/o/x populations. However, the reasons why Latina/o/x communities experience relatively lower suicide rates are not fully understood. Critical gaps exist in the examination of Latina/o/x suicide death, especially in rural settings, where suicide death by firearm is historically more common within non-Latina/o/x populations. Method: We tested whether the prevalence of Latina/o/x firearm suicide was meaningfully different in urban and rural environments and from non-Latino/a/x decedents when controlling for age, sex, and a social deprivation metric, the Area Deprivation Index. Suicide death data used in this analysis encompasses 2,989 suicide decedents ascertained in Utah from 2016 to 2019. This included death certificate data from the Utah Office of the Medical Examiner on all Utah suicide deaths linked to information by staff at the Utah Population Database. Results: Compared to non-Latina/o/x suicide decedents, Latina/o/x suicide decedents had 34.7% lower adjusted odds of dying by firearm. Additionally, among the firearm suicide decedents living only in rural counties, Latina/o/x decedents had 40.5% lower adjusted odds of dying by firearm compared to non-Latina/o/x suicide decedents. Discussion: The likelihood of firearm suicide death in Utah differed by ethnicity, even in rural populations. Our findings may suggest underlying factors contributing to lower firearm suicide rates within Latina/o/x populations, e.g., aversion to firearms or less access to firearms, especially in rural areas, though additional research on these phenomena is needed.

Accidental substance-related acute toxicity deaths among youth in Canada: a descriptive analysis of a national chart review study of coroner and medical examiner data. / Décès accidentels attribuables à une intoxication aiguë due à une substance chez les jeunes au Canada : analyse descriptive d'une étude nationale portant sur l'examen des dossiers des données de coroners et de médecins légistes.

INTRODUCTION: Substance-related acute toxicity deaths (ATDs) are a public health crisis in Canada. Youth are often at higher risk for substance use due to social, environmental and structural factors. The objectives of this study were to understand the characteristics of youth (aged 12-24 years) dying of accidental acute toxicity in Canada and examine the substances contributing to and circumstances surrounding youth ATDs. METHODS: Data from a national chart review study of coroner and medical examiner data on ATDs that occurred in Canada between 2016 and 2017 were used to conduct descriptive analyses with proportions, mortality rates and proportionate mortality rates. Where possible, youth in the chart review study were compared with youth in the general population and youth who died of all causes, using census data. RESULTS: Of the 732 youth who died of accidental acute toxicity in 2016-2017, most (94%) were aged 18 to 24 years. Youth aged 20 to 24 who were unemployed, unhoused or living in collective housing were overrepresented among accidental ATDs. Many of the youth aged 12 to 24 who died of accidental acute toxicity had a documented history of substance use. Fentanyl, cocaine and methamphetamine were the most common substances contributing to death, and 38% of the deaths were witnessed or potentially witnessed. CONCLUSION: The findings of this study point to the need for early prevention and harm reduction strategies and programs that address mental health, exposure to trauma, unemployment and housing instability to reduce the harms of substance use on Canadian youth.

Using death investigation data to better understand the overdose crisis. / Utiliser les données d'enquête sur les décès pour mieux comprendre la crise des surdoses.

INTRODUCTION: The collection of articles in this theme series of the journal presents results from a national chart review study of the death investigation files of people who died of acute toxicity in Canada between 2016 and 2017. This study endeavoured to better understand the characteristics of the people who died, the circumstances of their deaths and the substances involved. While information about the study and some of its findings have previously been published, we would like to share more about how the study came to be, the people involved and the value of collaborative efforts between coroners, medical examiners and public health practitioners.

Timely and comparable data are essential to the development of a robust evidence base that public health professionals can use to address the evolving national overdose crisis and its drivers. Key to developing this evidence base is fostering collaborative relationships between multidisciplinary teams, including the public health sector and the coroner and medical examiner community.

Il est essentiel de disposer de données comparables et à jour pour constituer une base de données probantes solide dont les professionnels de la santé publique pourront se servir pour lutter contre la crise nationale des surdoses à mesure qu'elle évolue et contre les facteurs qui en sont à l'origine. Le développement de cette base de données probantes repose sur la collaboration d'équipes multidisciplinaires, composées notamment de membres du secteur de la santé publique et des coroners et des médecins légistes.

What Are the Experiences of Mental Health Practitioners Involved in a Coroner's Inquest and Other Inquiry Processes after an Unexpected Death of a Patient? A Systematic Review and Thematic Synthesis of the Literature.

Grief after suicide or patient-perpetrated homicide can be complex for those involved in the patient's care. Mental health practitioners with patients who die unexpectedly may be called to assist in the formal investigation processes that follow. The aim of this study was to examine the experience of mental health practitioners called to attend a coroner's inquest or other forms of formal inquiry. A protocol for a systematic review was prospectively registered on PROSPERO (CRD42023400310). A thematic synthesis of existing literature was conducted. We identified six articles for inclusion and constructed three themes from our analysis: Blame and enduring hostility, In the dark, and Limited learning. We found mental health practitioners may construct narratives of self-blame. These can be reinforced by the investigatory processes that follow. Feedback from inquiries is often delivered haphazardly and may not reflect the realities of clinical work. The support given to assist practitioners through inquiry processes varied-both in amount and how helpful it was. The research conducted on this topic is limited. More qualitative research should be conducted to understand the factors that make this experience more or less difficult as well as well as what support is needed for whom.

Surveillance for Unexplained Deaths of Possible Infectious Etiologies During the COVID-19 Pandemic-Minnesota, 2020-2021.

OBJECTIVES: Surveillance systems for unexplained deaths that might have an infectious etiology are rare. We examined the Minnesota Department of Health Unexplained Deaths and Critical Illnesses of Possible Infectious Etiology and Medical Examiner Infectious Deaths (UNEX/MED-X) surveillance system,-a system that expanded postmortem surveillance for infectious diseases during the COVID-19 pandemic by leveraging standard (medical examiner [ME]) and expanded (mortuary) surveillance to identify COVID-19-related deaths. METHODS: MEs, coroners, or morticians collected postmortem swabs from decedents with an infectious prodrome or with SARS-CoV-2 exposure before death but with no known recent infectious disease testing. The Minnesota Department of Health Public Health Laboratory used nucleic acid amplification, viral culture, and standard algorithms to test specimens collected postmortem for SARS-CoV-2, influenza virus, and other infectious pathogens. We reviewed UNEX/MED-X data from March 2, 2020, through December 31, 2021, and characterized decedents by location of swab collection (ie, ME or mortuary). RESULTS: From March 2, 2020, through December 31, 2021, the UNEX/MED-X surveillance system received samples from 182 decedents from mortuaries and 955 decedents from MEs. Mortuary decedents were older than ME decedents (median age, 78 vs 46 y). Seventy-three mortuary decedents (40.1%) and 197 ME decedents (20.6%) had SARS-CoV-2 detections. The UNEX/MED-X system identified 212 COVID-19-related deaths, representing 2.0% of total COVID-19-related deaths in Minnesota. Eighty-nine decedents (42.0%) were from racial and ethnic minority populations, representing 6.1% more COVID-19-related deaths among people from racial and ethnic minority populations than would have been detected without this surveillance system. PRACTICE IMPLICATIONS: Expanded and standard UNEX/MED-X surveillance builds capacity and flexibility for responding to emerging public health threats. Similar programs should be considered elsewhere as resources allow.

The National Association of Medical Examiners Position Paper on the Investigation and Certification of Pediatric Deaths From Environmental Neglect.

ABSTRACT: Pediatric deaths that occur because of environmental neglect often involve 4 common scenarios: (1) hyperthermia due to environmental exposure, (2) ingestion of an accessible drug or poison, (3) unwitnessed/unsupervised drownings, and (4) unsafe sleep practices. Given the same fact pattern, the manner of death will vary from accident to homicide to undetermined based on local custom and/or the certifier's training and experience. Medical examiner/coroner death certifications are administrative public health determinations made for vital statistical purposes. Because the manner of death is an opinion, it is understandable that manner determinations may vary among practitioners. No prosecutor, judge, or jury is bound by the opinions expressed on the death certificate. This position paper does not dictate how these deaths should be certified. Rather, it describes the challenges of the investigations and manner determinations in these deaths. It provides specific criteria that may improve consistency of certification. Because pediatric deaths often are of public interest, this paper provides the medical examiner/coroner with a professional overview of such manner determination issues to assist various stakeholders in understanding these challenges and variations.

Opioid-related overdose deaths among people experiencing homelessness, 2017 to 2021: A population-based analysis using coroner and health administrative data from Ontario, Canada.

AIMS: To measure the change in proportion of opioid-related overdose deaths attributed to people experiencing homelessness and to compare the opioid-related fatalities between individuals experiencing homelessness and not experiencing homelessness at time of death. DESIGN, SETTING AND PARTICIPANTS: Population-based, time-trend analysis using coroner and health administrative databases from Ontario, Canada from 1 July 2017 and 30 June 2021. MEASUREMENTS: Quarterly proportion of opioid-related overdose deaths attributed to people experiencing homelessness. We also obtained socio-demographic and health characteristics of decedents, health-care encounters preceding death, substances directly contributing to death and circumstances surrounding deaths. FINDINGS: A total of 6644 individuals (median age = 40 years, interquartile range = 31-51; 74.1% male) experienced an accidental opioid-related overdose death, among whom 884 (13.3%) were identified as experiencing homelessness at the time of death. The quarterly proportion of opioid-related overdose deaths attributed to people experiencing homelessness increased from 7.2% (26/359) in July-September 2017 to 16.8% (97/578) by April-June 2021 (trend test P < 0.01). Compared with housed decedents, those experiencing homelessness were younger (61.3 versus 53.1% aged 25-44), had higher prevalence of mental health or substance use disorders (77.1 versus 67.1%) and more often visited hospitals (32.1 versus 24.5%) and emergency departments (82.6 versus 68.5%) in the year prior to death. Fentanyl and its analogues more often directly contributed to death among people experiencing homelessness (94.0 versus 81.4%), as did stimulants (67.4 versus 51.6%); in contrast, methadone was less often present (7.8 versus 12.4%). Individuals experiencing homelessness were more often in the presence of a bystander during the acute toxicity event that led to death (55.8 versus 49.7%); and where another individual was present, more often had a resuscitation attempted (61.7 versus 55.1%) or naloxone administered (41.2 versus 28.9%). CONCLUSIONS: People experiencing homelessness account for an increasing proportion of fatal opioid-related overdoses in Ontario, Canada, reaching nearly one in six such deaths in 2021.

An evaluation of naloxone transit for opioid overdose using drones: A case study using real-world coroner data.

BACKGROUND AND AIMS: Opioids are now the most cited class in fatal overdoses. However, the antidote for opioid overdose-naloxone-is not always readily available. Our aim was to evaluate the feasibility of naloxone transit via drone to provide rapid access at the point of care. METHODS AND FINDINGS: Real-world data pertaining to opioid overdoses, which occurred in the Teesside area of the UK 2015-2019, were extracted from the National Programme on Substance Abuse Deaths (NPSAD). The original locations of these opioid overdoses were used to compare the projected response times of ambulances with that of drones when considering the impacts of actual traffic and weather conditions, respectively; 58 cases were identified where a bystander-who could have called for and administered emergency naloxone-was likely present. RESULTS: In 78% of cases (n = 45/58) a class C1 commercial-off-the-shelf drone carrying naloxone could have reached the overdose location in 7 min-the benchmark time for the arrival of emergency services for Category 1 calls in England. With the implementation of recent advances in drone engineering, such as increased speeds and temperature-controlled cargo cradles, it is estimated that 98% of overdoses could have been reached in this timeframe (n = 57/58). Ambulances were able to reach a significantly lower number of cases in 7 min, even when considering best-case scenario traffic conditions (14%, n = 8/58, χ2 P < 0.001). CONCLUSIONS: This study provides proof-of-concept that, in the Teesside area of the UK, drones are more likely than ambulance to get naloxone to the site of an opioid overdose in 7 min.

Structural Bias in the Completeness of Death Investigations for Sudden Unexpected Infant Deaths (SUIDs).

OBJECTIVE: To assess sudden unexpected infant death (SUID) investigations for structural inequities by race/ethnicity and geography. METHODS: The SUID Case Registry compiles data on death investigations. We analyzed cases from 2015 to 2018 (N = 3847) to examine likelihood of an incomplete death investigation, defined as missing autopsy, missing scene investigation, or missing detailed information about where and how the body was found. We also analyzed which specific components of death investigations led to the greatest number of incomplete investigations. RESULTS: Twenty-four percent of SUIDs had incomplete death investigations. Death scenes in rural places had 1.51 times the odds of incomplete death investigations (95% confidence interval [CI], 1.19-1.92) compared with urban areas. Scene investigations led by law enforcement were more likely to result in incomplete death investigations (odds ratio [OR] = 1.49; 95% CI, 1.18-1.88) than those led by medical examiners. American Indian/Alaska Native SUIDs were more likely than other racial groups to have an incomplete investigation (OR = 1.49; 95% CI, 0.92-2.42), more likely to occur in rural places ( P = .055), and more likely to be investigated by law enforcement ( P < .001). If doll reenactments had been performed, 358 additional cases would have had complete investigations, and if SUID investigation forms had been performed, 243 additional cases would have had complete investigations. American Indian/Alaska Native SUIDs were also more likely to be missing specific components of death investigations. CONCLUSION: To produce equitable public health surveillance data used in prevention efforts, it is crucial to improve SUID investigations, especially in rural areas and among American Indian/Alaska Native babies.

Medicines and other factors causing deaths in English and welsh care homes: five-years of preventing future death reports by coroners.

BACKGROUND: Whilst information has been published on the impact, severity and causes of incidents involving medicines in care homes, it has not been systematically described. This review explored whether coroners' Preventing Future Death (PFD) reports involving medicines for people living in care homes could add to this evidence base. METHODS: PFD reports made publicly available between 2017 and 2021 classified as 'care home-related deaths' were reviewed. Reports describing medicines and/or medicines processes were identified. Contributory factors within these reports were then identified. RESULTS: Within the timeframe, 156 reports were published, and 25 described medicines (n = 27) or medicines processes (n = 5) concerning people living in care homes. The impact of medicines and/or medicines processes was quantified as no impact (n = 7), contributory (n = 6) and direct (n = 14) per report. Two key themes emerged. Four deaths had an association between their falls risk, prescribed anticoagulants, and the failure of the service to seek timely emergency care following a fall and two deaths concerned endocrine medicines, where people refused insulin or blood sugar monitoring and staff did not seek timely advice. CONCLUSION: This study demonstrated PFD reports provide an insight into the potential association between medicines, and other aspects of the person's care in causing harm.

The evolution of fentanyl-related substances: Prevalence and drug concentrations in postmortem biological specimens at the Miami-Dade Medical Examiner Department.

Since 2014, the Miami-Dade Medical Examiner Department (MDME) has observed a drastic increase in the number of fentanyl and fentanyl analog (fentanyl-related substances (FRSs)) fatalities since its introduction into the heroin and cocaine supply. Due to the prevalence of FRS in Miami-Dade County, the MDME toxicology laboratory began documenting each case in which fentanyl and/or a fentanyl analog was identified. Additional information monitored included demographics (age, race and sex), other drugs identified, cause of death (COD) and manner of death (MOD). From 2014 to 2022, the MDME toxicology laboratory analyzed a total of 1,989 cases that tested positive for FRS, of which 1,707 had detectable and/or quantifiable fentanyl concentrations in postmortem cases. The majority of decedents were white males (62%), and the predominant age range was 25-34 years. The most prevalent MOD was accident (93%) with the most common COD listed as acute combined drug toxicity of fentanyl in combination with other drugs (79%). Other drugs found in combination with fentanyl included heroin, cocaine (most prevalent), synthetic cathinones and ethanol. Of all FRS cases, 9% (170 cases) involved fentanyl alone as a COD, while 2% (38 cases) included only fentanyl analogs. Fentanyl concentrations ranged from 1.0 to 1,646 ng/mL in peripheral blood, 1.2 to 449 ng/mL in central blood, 3.2 to 28 ng/mL in donor blood (obtained during tissue harvesting), 1.1 to 108 ng/mL in antemortem blood, 8.5 to 1,130 ng/g in liver and 2.0 to 471 ng/g in brain. Drug concentrations were also reported for an additional eight fentanyl analogs. Considering the prevalence, high potency and constant evolution of FRS, it is important to continuously monitor trends and report drug concentrations in complex medical examiner casework in an effort to educate pathologists, law enforcement and local governments.

Evidence of autoinflammation as a principal mechanism of myocardial injury in SARS-CoV-2 PCR-positive medical examiner cases.

BACKGROUND: Disease from Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) remains the seventh leading cause of death in the United States. Many patients infected with this virus develop later cardiovascular complications including myocardial infarctions, stroke, arrhythmia, heart failure, and sudden cardiac death (20-28%). The purpose of this study is to understand the primary mechanism of myocardial injury in patients infected with SARS-CoV-2. METHODS: We investigated a consecutive cohort of 48 medical examiner cases who died with PCR-positive SARS-CoV-2 (COVpos) infection in 2020. We compared them to a consecutive cohort of 46 age- and sex-matched controls who were PCR-negative for SARS-CoV-2 (COVneg). Clinical information available at postmortem examination was reviewed on each patient. Formalin-fixed sections were examined using antibodies directed against CD42 (platelets), CD15 (myeloid cells), CD68 (monocytes), C4d, fibrin, CD34 (stem cell antigen), CD56 (natural killer cells), and myeloperoxidase (MPO) (neutrophils and neutrophil extracellular traps(NETs)). We used a Welch 2-sample T-test to determine significance. A cluster analysis of marker distribution was also done. RESULTS: We found a significant difference between COVpos and COVneg samples for CD42, CD15, CD68, C4d, fibrin, and MPO, all of which were significant at p < 0.001. The most prominent features were neutrophils (CD15, MPO) and MPO-positive debris suggestive of NETs. A similar distribution of platelets, monocytes, fibrin and C4d was seen in COVpos cases. Clinical features were similar in COVpos and COVneg cases for age, sex, and body mass index (BMI). CONCLUSION: These findings suggest an autoinflammatory process is likely involved in cardiac damage during SARS-CoV-2 infection. No information about clinical cardiac disease was available.

Preventable deaths involving falls in England and Wales, 2013-22: a systematic case series of coroners' reports.

BACKGROUND: Falls in older people are common, leading to significant harm including death. Coroners have a duty to report cases where action should be taken to prevent future deaths, but dissemination of their findings remains poor. OBJECTIVE: To identify preventable fall-related deaths, classify coroner concerns and explore organisational responses. DESIGN: A retrospective systematic case series of coroners' Prevention of Future Deaths (PFD) reports, from July 2013 (inception) to November 2022. SETTING: England and Wales. METHODS: Reproducible data collection methods were used to web-scrape and read PFD reports. Demographic information, coroner concerns and responses from organisations were extracted and descriptive statistics used to synthesise data. RESULTS: Five hundred and twenty-seven PFDs (12.5% of PFDs) involved a fall that contributed to death. These deaths predominantly affected older people (median 82 years) in the community (72%), with subsequent death in hospital (70.8%). A high proportion of cases experienced fractures (51.6%), major bleeding (35.9%) or head injury (38.7%). Coroners frequently raised concerns regarding falls risks assessments (20.9%), failures in communication (20.3%) and documentation issues (17.5%). Only 56.7% of PFDs received a response from organisations to whom they were addressed. Organisations tended to produce new protocols (58.5%), improve training (44.6%) and commence audits (34.3%) in response to PFDs. CONCLUSIONS: One in eight preventable deaths in England and Wales involved a fall. Addressing concerns raised by coroners should improve falls prevention and care following falls especially for older adults, but the poor response rate may indicate that lessons are not being learned. Wider dissemination of PFD findings may help reduce preventable fall-related deaths in the future.

Impact of changing from autopsy to post-mortem CT in an entire HM Coroner region due to a shortage of available pathologists.

A significant problem facing routine medicolegal coroner-referred autopsies is a shortfall of pathologists prepared to perform them. This was particularly acute in Lancashire, where the coroner decided to initiate a service that relied on post-mortem computed tomography (PMCT). This involved training anatomical pathology technologists (APTs) to perform external examinations, radiographers to perform scans, and radiologists to interpret them. The service started in 2018 and now examines over 1,500 cases per year. This study outlines the PMCT process using NHS staff, with CT equipment and logistics managed by the commercial sector. It compares the demographics and outcomes of PM investigations for two 6-month periods: the autopsy service prior to 2018, and then the PMCT service. These data were then compared with previous UK PMCT data. Referrals for adult non-suspicious deaths were made in 913 cases of which 793 (87%) had PMCT between 01/10/2018 and 31/03/2019. Fifty-six cases had autopsy after PMCT, so 81% of cases potentially avoided autopsy. The PMCT service did not delay release of bodies to the next-of-kin. Comparing the cause of death given shows no difference in the proportions of natural and unnatural deaths. There was an increase in diagnosis of coronary artery disease for PMCT, with less respiratory diagnoses, a feature not previously demonstrated. These data suggest PMCT is a practical solution for potentially failing autopsy services. By necessity, this involves changes in diagnoses, as PMCT and autopsy have different strengths and weakness, but the ability to pick up unnatural death appears unaffected.

Assessing Neglect in Pediatric Environmental Deaths: A Survey of Manner of Death Determinations.

ABSTRACT: There are 4 common types of environmental pediatric deaths that may involve various degrees of neglect: hyperthermia, ingestion, drownings, and unsafe infant sleep practices. Because the circumstances surrounding each are disparate, there is no set of standards by which these factors may be weighed and interpreted. Given the same facts, the manner of death certification may differ depending upon training/experience and/or local practice.To assess certification variations, 147 board-certified forensic pathologists were surveyed for the choice of manner in scenarios with different degrees of negligence intent. In addition to evaluating certification consistency, the survey examined whether certain factors affected the choice. The results demonstrated strong consistency in certain scenarios and widely disparate certifications in others.Medical examiner/coroner certifications are administrative decisions for vital statistical purposes. The manner of death reflects an evidence-based conclusion, but because it is ultimately an opinion, determinations may vary. Based on the survey, some certification criteria were identified (ie, intent, child age, and knowingly placing a child in an environment with a reasonable risk of harm). Using these criteria may improve consistency, but it is unreasonable to expect 100% concordance. Understanding the certificate's role helps to place the manner in the proper legal and public health contexts.

Prevalence of xylazine in overdose cases: An analysis of Miami-Dade County medical examiner case data.

Xylazine sedative, muscle relaxant, and analgesic used in a veterinary setting. Although xylazine was never approved for therapeutic use in humans, it has become popular in the street drug market as a cutting or bulking agent in the fentanyl and heroin supply. Recently, there has been a significant increase in the detection of xylazine in postmortem forensic toxicology casework. Xylazine can be identified during routine toxicology screening utilizing instrumentation such as gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry. Using the Miami-Dade Medical Examiner's LIMS system, all cases received between 2015 and 2022 in which xylazine was reported were reviewed. The cases studied include accidental drug overdose deaths in Miami-Dade County as well as Collier County (Naples), Florida. In total, there are 170 cases; the majority are accidental polydrug overdoses involving White males between the ages of 25 and 44 years old. Of the 170 cases, 37% listed xylazine as the cause of death. 13% of cases contained only xylazine and fentanyl while the remaining 87% of deaths were attributed to polydrug toxicity involving two or more substances. The prevalence of xylazine can be attributed to its increasing popularity rather than an increase in caseload. In 2019, xylazine was present in only 4% of all accidental fentanyl overdoses. By 2021, this percentage has increased sixfold, with xylazine present in 24% of all accidental fentanyl overdoses. Despite a decrease in fentanyl overdoses in 2022, the percentage of xylazine detection remained the same.

Preventable deaths involving opioids in England and Wales, 2013-2022: a systematic case series of coroners' reports.

BACKGROUND: Opioid deaths have increased in England and Wales. Coroners' Prevention of Future Deaths reports (PFDs) provide important insights that may enable safer use and avert harms, yet reports implicating opioids have not been synthesized. We aimed to identify opioid-related PFDs and explore coroners' concerns to prevent future deaths. METHODS: In this systematic case series, we screened 3897 coronial PFDs dated between 01 July 2013 and 23 February 2022, obtained by web scraping the UK's Courts and Tribunals Judiciary website. PFDs were included when an opioid was implicated in the death. Included PFDs were descriptively analysed, and content analysis was used to assess concerns reported by coroners. RESULTS: Opioids were involved in 219 deaths reported in PFDs (5·6% of PFDs), equating to 4418 years of life lost (median 33 years/person). Morphine (29%), methadone (23%) and diamorphine (16%) were the most common implicated opioids. Coroners most frequently raised concerns regarding systems and protocols (52%) or safety issues (15%). These concerns were most often addressed to National Health Service (NHS) organizations (51%), but response rates were low overall (47%). CONCLUSIONS: Opioids could be used more safely if coroners' concerns in PFDs were addressed by national organizations such as NHS bodies, government agencies and policymakers, as well as individual prescribing clinicians.
